SMC Networks IR1010 Operation Manual page 10

Warning
(1) When the Spring Holder is to be removed (see construction on page 6), reduce the set
pressure to 0 and shut off the supply pressure completely beforehand.
(2) If a pressure gauge is to be added, reduce the set pressure to 0 before removing the plug.
(3) Rubber parts such as diaphragm, o-rings and seals are consumption, and should be
replaced every three years. If the fixed orifice is exposed to contamination from extended
use of the precision regulator, the product may not operate within specification. It is
recommended checked every year, and replacing the part every three years.
(4) Ensure to exhaust the condensate of the filters installed on the supply (upstream) side,
wash the element and pipings, and perform replacement regularly. Although it depends
on the operating conditions, the guideline is every month or every three months.
(5) When removing the equipment for maintenance, contamination may enter the pipe and the
precision regulator. Please flush the pipe and fittings thoroughly with air before
reconnecting them to remove the foreign matter or contamination from the piping
materials.
(6) When remounting the valve guide after removing it for maintenance, use a tightening
torque of no more than 0.6 N m. Since the valve guide on this product is made of resin,
there is a danger of damage if tightened with a torque exceeding the prescribed valve.
Warning
(1) Connect piping/fittings using the recommended torque while holding the product tightly.
Loose or faulty sealing can occur if tightening torque is insufficient, while damage to the
thread can occur if over tightened. If the product is not held while tightening, excessive
force will be applied to the product bracket, causing breakage.
